I'm looking for a stand for my motarded WR450F. The stock cast aluminum stand has a continuously taporing c-section most of its length, so removing an inch or two from the center doesn't seem feasible. I can tell that a few mods will need to be made to accommodate the 250X stand, but I want to make the length is right before proceeding, so... What length is the stand from the swivel bolt center to the end of the pad? Is the stand aluminum or steel? Thanks for your help!
